Description

A child seat for attachment to a vehicle seat

The present invention relates to a child seat for attachment to a vehicle seat according to claim 1.

In the prior art, a child seat is known to attach to a vehicle seat. These child seats can have their own belt system or can be designed to attach to the belt system of an automobile. Typically, such a child seat includes at least one seat shell (seat area) and a backrest. In addition, such a child seat may have a headrest or footrest or other components.

In this context, in the context of the present invention, the term "child seat" should be understood as a generic term for "classic" child car seats and baby carriers. Therefore, unless otherwise stated, the features provided in the child seat in connection with the present invention are basically applicable to baby carriers, and vice versa. The same applies to the term "child" and is understood as a generic term for infants as well as children and babies.

The so-called "baby carrier" often includes (separately) an integral shell for accommodating a baby or child, and may include a separate belt system, optionally a headrest and possible additional components. This "baby carrier" has a back section adjacent to a "seat area" that can accommodate the buttocks of a child, instead of a backrest (structurally depicted).

Generally, it is known that a child is fixed to a child seat by means of a three-point belt of a car or a belt (for example, a five-point belt, a chest belt, etc.) provided on the childsheet itself. In this case, the belt can be guided in the opposite direction of the pelvis beyond the shoulder of the child on the seat. However, two straps may also be provided, each guided over one shoulder. It is known that in the case of a seat with at least its own belt system, the position of the belt system can be adjusted to the size of the child. In particular, solutions are known in which the various positions of the belt system can be locked through the positive engagement of a suitable member, for example a toothed rack.

What is common to these known systems is that the child on the seat - if the car crashes - first moves further due to inertia and then suddenly brakes by the strap. However, the child's head continues to move, which can lead to pitching motion and jaw impact on the chest, which can result in dangerous injuries, such as in the neck spine.

For this reason, it is generally desirable to limit the acceleration of the child and to absorb the peak of the force. For this purpose, corresponding force limiters capable of absorbing force peaks are known in the prior art. For example, DE 10 2005 038 814 A1 proposes the use of a hydraulic member which increases the energy absorption capacity of the belt when the belt is loaded upon impact. EP 0 805 066 A2 proposes a torsion bar capable of plastic deformation, which, when impacted, absorbs energy or intercepts force peaks.

DE 10 2005 025 570 A1 also proposes the use of plastic-deformable components, in particular holders for straps with areas for deformation. As supplementary force-restricting means, tear seams are referred to as belts, releasing the belt section in a defined manner when excessive force is applied so that the body of the child in the seat moves further forward So that the deceleration energy can be reduced. In DE 10 2005 025 570 A1, a complete replacement of the force limiter must be made to adjust the size or weight of the child. DE 101 07 874 A1 also discloses a plastic deformation force-limiting means in which the force-limiting threshold changes as a function of the set belt length or position. To this end, for example, several deflections with different material thicknesses are provided. By reattaching the belt system to another deflecting device, the force-limiting means according to DE 101 07 874 A1 must be adjusted to the size or weight of the child.

In general, it is considered disadvantageous that adaptation (if possible) of force-limiting means to the size or weight of a child should always be performed in relatively complex steps in the prior art. Thus, when moving the strap in accordance with DE 101 07 874 A1, as well as when replacing the holder according to DE 10 2005 025 570 A1, the belt system must be newly installed, for example dismounted and re-threaded do.

It is an object of the present invention to provide a child seat for attaching to a vehicle seat that realizes a limitation of force in a simple and safe manner in the event of an impact.

This object is achieved by a child seat according to claim 1.

More particularly, the object is achieved by a seat assembly comprising a seat region and a back section (backrest), at least one shoulder strap, at least one retaining devic for retaining and deflecting the shoulder strap, When the predetermined limit force exerted by the strap (or by the shoulder straps if a retaining device is formed to hold and / or deflect the two shoulder straps) is exceeded, a first arrested position Limiting means designed to be moved from the first restraining position to the second restraining position (such that the force to hold the child is reduced or the energy is absorbed). do.

The key idea of the present invention is that the holding device can basically take two (predetermined) positions, wherein the second position (in case of an accident) is reached only when a predetermined limit force is exceeded. Thus, the (total) holding device is displaced to absorb the peak of the force or to absorb the energy upon impact. The retaining device is (preferably) dimensionally stable during this displacement (and thus does not alter the shape). The force-limiting means is preferably designed to maintain the retaining device in the second position when it reaches the second position and the body of the child is stopped (i.e. after the impact) and no force is exerted from the shoulder strap. In both the first position and the second position, the retaining device is preferably latched (in particular in a form-fitting manner), i.e. in a first or second latching position. Overall, the force-limiting means and the holding device are preferably configured such that at least one component of the force acting on the holding device acts in the direction of the connecting line between the individual (latching) positions. The latching (locking) is preferably interlocked, but may alternatively or additionally (at least partially, perhaps completely) occur in a force-locking manner. As a result of the (predetermined) locking position (in particular the latching position), on the one hand the force peaks can be cut off in a simple manner, while the shoulder straps remain securely and reliably before and after the impact. Also, since at least one force-limiting means is characterized by a simple structure, manufacturing costs are reduced.

In a particular embodiment, at least one adjustment device is arranged in at least two different positions, in particular at least the back section (back), to adjust the belt length and / or position to the size and / or weight of the child in the child seat. (In particular, the latching position) of the first and second locking positions. As a result of this adjustment device, the child seat can be easily adapted to the needs of the child. In a preferred design and in particular a simple design, the displacement from the first position to the second position can take place on the one hand by the actuation of the adjusting device (e.g. via a handle) and on the other hand by the action of the force- Lt; / RTI > This structure is especially simple and protects against shocks. The adjustment device is particularly directed to a height adjustment device, which allows the child seat to be adapted to the size of the child. For this purpose, the retaining device can be locked in various (latching) positions.

Preferably, at least one latching device is provided and via the latching device the holding device can be fixed in at least two positions (above), in particular coupled to at least two latching positions (above). In particular, at least two complementary latching members may be provided for this purpose (e.g., projections, particularly bolts and corresponding recesses, in particular pockets). Basically, the locking can be performed through interlocking and / or friction connections. For example, the locking member may engage the pocket-like structure, and optionally the individual pockets are separated from each other by at least one web (or the like). It is, however, also possible for the locking member (protrusion) to engage in a toothed strip (or its receptacle) or a perforated strip (or its aperture) or any other suitable structure. In any case, this locking allows stable and easy fixation of the retaining device at each position, increasing safety in the event of an accident. In particular, the discrete locations are preferably connected by separate receptacles (particularly pockets) and / or projections and / or (continuous or disconnected) connecting webs, which are components of the essential components, and / or by serration strips and / .

In a preferred embodiment, the holding device can be moved in at least three positions (preferably via a regulating device), and when the first limiting force is exceeded, the next position is taken, and when the second limiting force is exceeded, A separate position is taken. In general, multiple (latching) positions can be continuously overcome with sufficiently long action and sufficiently large force. As a result of each transition from one position to an adjacent position (e.g., each web being positioned between two receptacles, and in particular pockets), force-limiting means can be provided. This embodiment allows a very simple ("automatic") setting of force-limiting or energy absorption. For a smaller or lighter child, only the following positions may be taken (in the case of impact), one position may be taken for the larger child, and the next position may optionally be taken for the larger child. Therefore, no further power-limiting need be set by the user in relation to the size and weight of the child (there is a corresponding risk of incorrect operation). The child seat is thereby designed in its own "adaptive" manner. As a result, the problems existing in the prior art can be reduced in a simple manner even with a particularly significant force peak occurring due to incorrect operation.

Preferably, the retaining device is connected to the headrest and / or displaceable with the headrest. In this case, when the headrest is adapted to the size of the child, the shoulder strap can be easily and reliably adapted to the size of the child. This also increases safety in the event of an impact.

In certain embodiments, the adjustment device is particularly preferably capable of having a handle for unlatching of the locking. Optionally or additionally, a spring, in particular a return spring, can be provided to create the locking. This allows simple and quick adjustment of the retaining device and possibly (height) of the headrest.

For example, for regular adjustment of the locked belt system, the locking member may be moved from the corresponding pocket (e.g., by pulling the handle against the spring force), and then the position of the belt system may be desired And the locking member can move back into the pocket (e.g., by the action of a spring force, possibly by releasing the handle). Preferably, the unlocking may also occur when the seat is installed in the vehicle and the child is seated on the seat, for example a handle, possibly a lever and / or a switch, etc. may be attached to the top of the seat for unlocking the height adjustment It is always accessible.

Preferably, the force-limiting means is formed by a region between the locking positions (e.g., by a pocket or protrusion of the serrated strip or by a web between teeth). More preferably, at least one section (e.g., pocket or generally recess) between the two latching devices can be plasticized or resiliently deformed when the limiting force is overcome or broken, have. Generally, it is desirable to design such an intermediate section to move to an adjacent position (in the direction of the connection line between the individual locking positions) when a force exceeding the limit force occurs.

In certain embodiments, at least one web is disposed between two latching devices (e.g., pockets), and the holding device is preferably moved from one position to another position, Plastic deformation occurs. More preferably, a plurality of webs (and associated three or more latching devices, in particular three or more pockets) are provided, and the webs are made in different thicknesses. Such webs can easily and effectively provide force-limiting means. If a plurality of webs are provided with different thicknesses, a different limiting force to be overcome may be set depending on the respective position in which the retaining device is placed. The thickness of the web can increase in one direction. For example, if four webs are provided, these four webs are arranged in the order of a first web, a second web, a third web and a fourth web, and each subsequent web (e.g., a third web) May each be formed thicker than the previously disposed one (e.g., the second web). In this configuration, in particular, the thickest web is provided with a high limit force when the retaining device is located at a relatively high position (corresponding to a tall or heavy child), then the retaining device is moved to a somewhat lower position Or a light child), a lower limit force is provided. Generally, (with multiple webs) they can be formed with different thicknesses. However, they are believed to be formed by different materials, which are different in terms of resistance (or against deformation or fracture). If desired, a plurality of webs (or disconnected webs) may alternatively be provided, although exactly one web may be optionally provided between the two latched positions. Instead of a web, a spring, particularly a leaf spring, which is elastically deformed in the event of an impact and allows movement to another (latching) position exceeding the limit force, may be provided, for example. Other means for elastic deformation (instead of leaf spring) can be considered.

In a particular embodiment, the retaining device can be moved (preferably through an adjusting device) to at least three (locking) positions, i.e. at least first, second and third positions. Preferably, the limiting force defined by the structural design (e.g., selection of material and / or thickness) of the middle region, particularly for moving from the first position to the second position upon impact, (Or small) by at least 5%, preferably at least 10%, of the limiting force for movement to the position. Preferably, the first position is the highest position, the second position is the intermediate position, and the third position is the lowest position of the holding device. Overall, this allows user-friendly and safe adjustment of force-limiting.

In a particular embodiment, the at least one force-limiting means comprises an inclined surface which is designed and arranged such that when the limit force is exceeded, the locking member (only) is slid from the locking (bolt engagement) position, and the inclined surface is the locking member or bolt receptacle Or the like. Thus, force-limiting can be provided in a simple manner.

In a more specific embodiment, the force-limiting means has an at least partially convex or trapezoidal locking member. This also allows force-limiting to be provided in a simple manner.

In general, the force-limiting means may comprise at least one spring, in particular a leaf spring. With such a spring, the child-seat (after impact) will return to its original state, as the force-limiting means can be realized by elastic deformation (except that a predetermined locking force is exceeded, ).

Basically, the limit force should be adjusted to the weight of the child. The limiting force may be at least 500 N, preferably at least 1000 N, particularly preferably at least 1500 N and / or at most 21000 N, preferably at most 17000 N, more preferably at most 15000 N. Generally, a load of about 50 grams (i.e., 50 times the acceleration due to gravity) for at least a short time during impact can be tolerated. Thus, the measurement of the force threshold advantageously results in this restriction and the weight of the child. For a child seat, the maximum allowable weight may be 36 kg. For example, for a baby carrier, the minimum weight may be about 2.5 kg. For different limiting forces (with two or more locking positions or corresponding force-limiting means), the limit force at the highest position may be in the upper limit range (e.g., in the range of 12000 to 21000 N) The force may be in the lower limit range (e.g., 500 N to 11000 N). Optionally, another force threshold (limit force) for the force-limiting means may be obtained (e.g. by pulley-type deflection). In any case, the load of the child placed on the seat should be limited to 40 to 60 g, preferably 45 to 55 g.

According to a general idea, the position of the retaining device, which can be intentionally adjusted by the adjusting device (before actuation), differs at least in part from the position which can be taken at the time of impact by the action of at least one force-limiting means. For example, there may be a separate latching device on the one hand for the desired setting and on the other hand to limit the force. In certain embodiments, the adjustment device may include an adjustment element that is configured to define a plurality of positions to adjust the strap length or position and to assume a different position when the limit force is exceeded (by itself). Alternatively, the force-limiting means may comprise a force-limiting member for displacing the retaining device from the first position to the second position when a predetermined limiting force acting on the retaining device is exceeded, the force- Itself) can be moved to a plurality of positions. Thus, in this embodiment, the change of position due to exceeding the limit force at the time of impact is not the same as the corresponding position movement, which is intentionally performed for height adjustment of the retaining device. Due to the separation of these different position changes, particularly effective and stable adjustment of both force-limiting and strap length or position in the event of an accident is possible (before driving).

Other embodiments of the invention will be apparent from the dependent claims.

In the following description, the same reference numerals are used for the same and equivalent parts.

BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 shows a cross section of a child car seat without force-limiting means according to the invention. The section may be, for example, a structure arranged on the rear face of the child seat, especially on the back of the backrest or the back section. 1A and 1B show a structure for adjusting the holding device 29 (here not shown - see Figs. 13 to 15) for the shoulder strap in relation to its position, in particular the height. To this end, a (receiving) pocket 10 is provided, into which a locking member 11 can be coupled. The locking member 11 can be received in each of the respective pockets 10 (in Figs. 1A and 1B, for example from the top to the second pocket 10). The locking member 11 is also part of or at least connected to such a retaining device for the shoulder strap. In principle, if two shoulder straps are provided, the shoulder straps can each be retained in a separate retaining device, but preferably the shoulder straps are retained by one retaining device 29 (see Figures 13 to 15) do.

Fig. 2 shows a cross section similar to Fig. 1a of a child car seat according to the invention. The structure according to FIG. 2 differs from the structure according to FIGS. 1A and 1B by providing a (relatively thin) web 12 between individual pockets (in particular a second pocket from the top to a second pocket from above) Do. Webs 12 can be formed such that they can be plastically deformed or even broken when exceeding a limiting force (such as occurs in an accidental event), so that the locking member 11 can be moved to the next position For example, the second web 12 can be broken from above in the event of an accident, allowing the movement of the locking member 11 in the third to fourth pockets (from above). Further, according to Fig. 2, force-limiting means is formed (as in the corresponding separation area 12 in Figs. 1A and 1B), since it does not allow release of the locking by the locking members in each pocket even at the maximum force The separation region 13 is additionally provided between the two uppermost and the two lowest pockets 10, For example, these isolation regions 13 also resist a force (acting in the direction of the next pocket) greater than or equal to 21000 N, preferably greater than or equal to 25000 N.

In another embodiment (compare with the embodiment according to Fig. 2) according to Fig. 3a, the web is partially "taken out ". In other words, each web 12 (according to Fig. 2) is replaced by two projections (web projections) 14 which are directed towards each other. The pocket 10 may be formed by four projections 14, for example. The protrusion 14 may be either a straight end 15 (as shown in Figure 3a for the four upper protrusions 14) or a beveled end (as shown in Figure 3a for the four lower protrusions 14) 16). In general, the beveled end may prefer to slide from the locking member 11 to the next position (thus, the lower limit force is sufficient to move to the next position). In particular, various limit forces (force thresholds) can be set at different tilt angles. For example, each end of the projection 14 may extend in a top-to-bottom gradual flattened manner.

Figure 3b shows in further detail a perspective view of an embodiment similar to Figure 3a. In particular, it can be seen that instead of the individual protrusions 14, a pair of protrusions 17 can be provided, and the pocket 10 can be defined by four pairs of protrusions 17. In addition, the pocket 10 can be formed by two projection pairs 17 and an isolation region 13 (insulmountable). In addition, the pocket 10 can be formed by two (non-overlapping) isolation regions 13.

Figure 4 schematically shows another embodiment of the present invention. In particular, instead of the projections (web projections) shown in Figs. 3A and 3B, it is shown that the elastic projections 18 can be formed. Further, the projection 14 can be replaced by a leaf spring 19 (or another spring) also shown in Fig. In general, the used protrusions can be plastic or elastically deformed or even broken (when overcoming the force threshold).

Figure 5 shows another embodiment of a section similar to Figure 1b. Here, the web is geometrically designed (specifically by slight tilting of the side with the force applied) so that a large component of the applied force presses the locking member against the web, and a small component lifts the locking member from the pocket. If the force threshold is exceeded, the small force component overcomes the frictional resistance caused by the large force component and the locking element 11 is lifted from the pocket 10 or slips over the slope 20 to the next pocket. In a corresponding manner, a solution for a serrated or perforated strip or the like may be provided.

The webs or protrusions (web extensions) 14 shown in Figs. 6A-6C can be connected to the one and the bottom surrounding structure. However, they may be connected on only one side (preferred) or on the other side. Alternatives to arranging on only one side are shown in Figs. 6A to 6C and Figs. 7A to 7C (see Fig. 7C in particular). 6A to 6C and 7A to 7C, the projections (web inserts) are attached (connected) only in the lateral direction. As a result, the protrusion hangs freely in the space, so that the protrusion can be easily deformed or broken so as to facilitate the movement of the locking member to the next position.

8A is a detail view similar to FIG. 2, i.e., with the locking member 11 having a straight end 21. Alternatively, the locking member 11 may have a sloping end 22, so that the force acting on the projection 14 will cause an increased surface load on the web 14, Thereby facilitating deformation or breakage. In general, the geometric shape of the locking member can be selected so that the applied force increases the point or area load in the region between the locking positions and facilitates elastic or plastic deformation or breakage. This can also be achieved, for example, by a trapezoidal structure (see Figures 8b and 8c). It is also possible to form the force-loaded side of the locking member 11 convexly. Further, the locking member can be formed to be elastically deformable.

In yet another embodiment (see FIG. 9), only a certain number of locking positions can always be overcome before a non-overlapping position is again assumed. This can be realized, for example, by setting only the individual intermediate areas 23 between the pockets 10 so that they can be overcome to the next position. For example, every third or fourth intermediate region 23 can not be exceeded (see FIG. 9).

In an alternative embodiment, an additional component 24 is used, which can be used in a height-adjustable manner (but without force-limiting means) - in particular via a locking member 11b And in turn define several positions for locking the belt system including the force-limiting means. In a preferred embodiment, the belt system may initially be locked at the highest position in the component 24 at all times and may be moved to another position only when the limited limiting force is exceeded. For example, the component 24 has a pocket 10a to which the locking member 11a can be coupled for this purpose.

In another preferred embodiment (see Fig. 11), the limiting force to which force-limiting is applied is not the same at all locations, but depends on the position at which the belt system is locked. Thus, taking into account the correlation typically present between the child's height and weight, an explanation may be taken of the need to take into account the weight of the child within the seat when selecting the force threshold. In various embodiments, this can be done by appropriate choice of the web thickness (Fig. 11) and / or the length of the residual web insert (projection) and / or the material thickness of the spring and / or the spring strength and / or angle of the slope.

In principle, the various embodiments may be combined with one another as desired. By way of example, web projections (projections) of different lengths can be connected to a locking member having a concave side surface (see Figs. 12A and 12B).

In addition, the solutions and structures described above can be moved, for example, to a serrated or perforated strip or other suitable structure that allows interlocking and / or force-locked engagement, for example.

Figure 13 shows a side view of an embodiment of the present invention comprising a seat region 25, a back side section 26, a belt system 27 having a shoulder strap 28 and a retaining device 29 for holding and deflecting the shoulder strap 25. [ And Fig. A retaining device 29 is connected to the locking member 11 and the locking member can in turn be coupled to the pocket 10. Figure 14 shows an enlarged view of Figure 13 with retaining device 29 and locking member 11. In the holding device 29, a belt guide 30 is arranged, through which the belt can be guided to be held and deflected. Fig. 15 shows the stepped section of the section according to Fig. 15, the force acting on the retaining section by the shoulder straps 28 acts in the direction of the arrow 31 (i.e. essentially at least in relation to the component), i.e. in one direction of the arrangement of the pockets 10.

In addition, the details of the adjustment device which allows deliberate setting of the position of the holding device, in particular the height of the holding device, are recognized in Fig. Specifically, the adjustment device moves the locking device from its receptacle (pocket) against the action of the spring 34 (shown in Figure 14) when rotating about the axis 35 (counterclockwise in Figure 15) (Claw-shaped) actuating member 32 that pushes through a stop 33 (e.g., an arcuate stop). The actuating member 32 has a hook-shaped, possibly undercut section 36, which secures the locking member against unintentional unlocking.

Generally, the force or at least the component acting from the shoulder strap on the holding device upon impact acts preferably from top to bottom (parallel to the back), but also from bottom to top (according to a particular embodiment of the belt guide) . An intermediate position is present and the locking member may be moved from the lower position to the upper position and from the upper position to the lower position (or a corresponding force may be applied).

Overall, the child seat is provided with a safety-enhanced force-limiting means. In particular, the force-limiting means allows optimal force-limiting means to be "automatically" provided, especially when the belt layer is precisely adjusted. In this case, since the plurality of force-limiting means can operate continuously, the limiting force can be selected to be lower than in the prior art.

At the same time, the solution according to the invention can be carried out in a separate step without the selection of the force-limiting means, and with the adjustment of the belt position, optionally with automatic adjustment of the headrest, to provide. This setting is often necessary anyway when using child sheets. In particular, the setting of the limiting force does not need to be done any further, as the child seat must be removed, such as by reattaching or threading the strap, as was customary in the past. Rather, the setting can be made conveniently at the front, for example. It can be set during use with proper design.

Finally, the solution according to the invention is also particularly simple since its realization is possible with less effort compared to conventional solutions. For example, the hydraulic member can be completely removed. In addition, the force-limiting means can be achieved only by the deformed shape of the conventional locking mechanism, for example. In principle, no additional parts are required, and all parts can be manufactured using conventional manufacturing processes such as injection molding, extrusion blow molding, and the like. There is no effort by separate installation.

In this respect, it should be noted that all the above-mentioned parts are claimed solely and in any combination, in particular the details shown in the drawings, being essential to the invention. The variations are familiar to those skilled in the art.
